You can't see speeds for the app store specifically, but you can see overall network utilisation in Activity Monitor. Lion is maxing out my crappy rural ADSL at about 5 Mbps.

PS. If you're getting slow speeds, you might want to make sure you're using your ISP's DNS rather than something like Google DNS or OpenDNS, as using them can confuse Akamai as to where you are and result in slower downloads[/url].

Pludging is not going well. I started the download, left for 45 minutes and came back to what appears to be a totally hard-locked Mac. The CPU fans are spinning full speed, but the display is off. This is on a 2011 13" MBP.

EDIT: So, I shut it down and restarted. It came up OK, and it looks like the download completed. No idea what caused the lockup, but I'm actually starting the install now.

Downloading now, but it is definitely not as fast as Apple downloads normally are. Only getting ~2.4MB/s when I can usually get ~10MB/s. Then again someone else could be saturating the bandwidth here at work :\

no, but Trim Enabler 1.1 seems to work (at least, it ran, i haven't restarted yet).

the "natural scroll direction" drove me crazy immediately. i'm so used to these changes being non-optional that, instead of trying to find a preference to turn it off, my first instinct was to find a third party hack. it's going to take me a while to get used to all of the gestures. launchpad seems worthless. otherwise, it seems to run fine. i'm not a fan of the iOS like bouncing when scrolling in Safari, but i'm sure i'll get used to it.

3.75 GB. On my wired system (2011 MBP) it took 40 minutes, and the pludge has already occurred. On my old MBP (2006) over wifi, it says it's going to take an hour. It's been amazingly painless, so far.
